Suppressors OSS HX-QD 762 - Anyone here have hands on experience?

[Movistar]

I've ran the OSS HX-QD Ti on a few different rifles, currently its on my .300 BLK SBR. The first thing I did was test host rifle accuracy using my 18" 6.5 CM bolt gun. I was impressed with the result and like their QD mount. I haven't always had great results with QD mounts on precision rifles. While I had it on the bolt gun I noticed the recoil pulse was more like a muzzle brake vs. a traditional suppressor and suppression performance seemed to lack versus others. Granted on bolt guns back pressure/carrier timing and things like that are a non issue.

On my .300 BLK using sub-sonic ammo the suppression was not on par with a Rugged Surge 762 but not as noticeable when shooting supersonic ammo. My rifle will cycle with subsonic & supersonic ammunition, with or without the suppressor attached. The amount of gas in your face with the Rugged vs OSS is very noticeable.

On a friends LaRue the suppressor did outstanding in host rifle accuracy and POI return but did have issues cycling reliably. I touched base with Randy at OSS and he mentioned incidents where using the suppressor actually slowed carrier speed. I haven't had the opportunity to re-test it using different ammunition. Suppression on the LaRue with the OSS seemed to be on par with the other suppressors we had out that day including a KAC and Surefire. I don't have metering data so comments regarding suppression are subjective.

JF I realize this post is older but those 3 cans are the 3 I am basically considering one of at the moment.

Any comment on sound to the shooter between them? Will do 300blk SBR, 16 inch 6.5 AR and bolt gun.

Thanks!

Yet another metering video showing the OSS doing quite poorly:

We are talking 146-149db at the muzzle, and 145db at the shooter's ear AVERAGE (on a 10.5in 5.56 and 18in .308). And as he states, there is also more flash than traditional cans.

On the AR15/AR10 there is zero reason to buy one of these cans if you can run an adjustable gas block, you will simply get better performance in all metrics with a traditional can as a bunch of other people have pointed out time and again.

 

[Movistar]

Discussing metering at the EAR

 

[LeadZeke]

Yeah, that is true without an adjustable gas block. With an adjustable gas block the story is quite the opposite on AR10s/AR15s as shown many times, here is one such example:



There are many more on their channel and other from which only one conclusion can be drawn: and OSS is strictly inferior if you can run an adjustable gas block.

 

[Movistar]

None of the factory rifles I own/owned have an adjustable gas block. I have several uppers with adjustable blocks. So OSS would help They are good but I don’t think it works the way you’re suggesting. OSS is talking about gas coming back down the barrel which and adjustable block will do nothing about. Right?

 

[LeadZeke]

I'm not "suggesting" adjustable gas blocks work that way, I'm linking to irrefutable evidence that shows exactly how they work. Another poster linked to a thread on the first page that has more detail, but I'll break it down in text:

OSS is talking about gas coming back down the barrel which and adjustable block will do nothing about. Right?

Wrong. The adjustable gas block dramatically slows the unlocking of the bolt by limiting the amount of gas (and in the Superlative Arms block case also by lowering the pressure) allowed back to the carrier. This means the chamber is at much lower pressure when it finally does unlock, which means much less gas and noise to the shooter. The OSS just doesn't increase the pressure to begin with (much), but they make a lot of sacrifices (as shown above) to achieve that. The adjustable gas block achieves similar results in terms of lowering pressure, but with all the added benefits of a traditional can. That is the whole point of adjustable gas blocks. That is why you have everyone like the lead engineer at Dead Air recommending them.

 

[Movistar]

Gas absolutely comes back down the barrel with a can on. Adjustable is great. But they aren’t perfect. Most of them are “tunable” because after a few rounds they Carbon lock into place. I’ve had two do that. But I feel like you’re missing the point. If it’s quieter at the ear than a baffle can, and pretty much everyone who buys one likes it... it feels pointless to argue because so many people have their minds made up already.

I don’t know how to link a video. I’m not affiliated with OSS and I don’t own one. I am in the market for a new 762 to use on a semi auto 308 and 6.5CM like the SR25. I want a factory rifle.

Anyway. Oss posted a video of them putting their cans on all the various mods like adjustable gas block and carrier etc. you should check that out. I’m a skeptic to lead all skeptics. But you can see the “white shirt” test clearly.

It’s the “no weapon mods” video on their website

Unfortunately I wasn’t able to run the three suppressors on different platforms. That day accuracy testing the OSS was our focus.

 

[Lmatt]

If I could pick mine up from the dealer I could at least give you my opinion on the sound level between an ultra 5 and the 7.62 ti. Should be able to get the ultra any day now(stamp cashed 12/04/18. The OSS will probably be early 2020(stamp cashed 3/23/19) I wanted to try the OSS because I have a couple of x-95s and I thought it might be better on the ar10s.

 

[Lowlight]

The whole,

How does it sound debate, with a suppressor with a precision rifle is stupid to begin with.

We are shooting full-power loads and looking to maximize accuracy out of the system, the sound is not even secondary, it's 3rd.

If I am 600 yards away, the sound does not matter, and at my ears, I am shooting power loads anyway so it will be louder for sure.

With Blackouts and short-barreled AR stuff you are kicking doors down with, sure you can make an argument for the sound quality of a suppressor because the accuracy side of things is secondary. The techniques used to makes suppressors sound quieter often negatively affect accuracy. If you want accuracy you often give up a bit of suppression.

Who cares if it is a couple DBs louder, usually what people key on is the tone, not the pure sound numbers.

I want accuracy, I want repeatability, I want a good can that will not open up my groups.

I like the OSS Cans, I have 3 here and all have been excellent

You seem to have utterly failed to comprehend my post, or consult the videos. Since you seem to be having difficulty grasping the slightly technical nature of the posts, I'll simplify it more for you:

All suppressors increase the amount of gas coming back down the barrel. OSS increases it far less than others.

An adjustable gas block does not reduce the amount of gas coming back down the barrel. Instead it delays the unlock of the bolt till most of that gas has gone out the muzzle end and the pressure is significantly lower. Less pressure means less gas coming back out of the chamber.

Does that make sense to you now?

As to your other points:

1.) Stop buying shitty gas blocks. Superlative Arms do not have those problems.

2.) This is not an argument, this is you rejecting data you don't like. The facts are the facts, and the facts are simply that a traditional baffle can is superior in every way on an AR15 (or bolt gun) IF YOU PAIR IT WITH AN AGB. As is clearly shown by all the tests, the adjustable gas block will reduce at the ear db by 4-7db. If you don't run one (and none of the people you mention are) then yes, the OSS will (probably, depending on the host and competition) deliver a better experience.

3.) OSS puts out a lot of unsavory marking pieces. In the linked test, they specifically switch to a very high back pressure can and do not use a quality adjustable gas block when making the comparison.

4.) It is highly ironic that you are quoting corporate marketing while trying to dismiss some of the most legit independent testers that publish public data out there (suppressed nation).

A real skeptic would not be doing such things FYI.

Haha! Okay man. Yeah I failed to utterly comprehend your expertise on the matter. We are actually saying the same thing about how the gas block works. I understood it long before you felt the need to tell me I didn’t. It’s like you don’t really get it. Like you’ve got something totally against OSS. Maybe you work for a competitor? Do you have any real world experience yourself or are you in the same place I am, relying on video reviews and second hand info. I’ve watched every video I can find on this product trying to arrive at my own conclusion. Including the “unsavory” OSS videos as well as the few you’ve linked (prior to you linking them, I had already seen them).

How do you explain Alabama Arsenal, MAC, NFA review, JFComfort and our very own lowlight to name a few all speak well of them after actually using them. There’s more to life than a decibel or two. Your argument that an adjustable gas block makes this can useless doesn’t hold any water. 308 isn’t EVER going to be “hearing safe” it’s just loud.

I want a 762 that:

1. Is accurate and repeatable
2. Awesome mount system
3. Can go on a FACTORY RIFLE (in this case likely a KAC SR25 or HK MR762) and not effect the internals
4. Sounds good
5. Reasonable weight added

Is your answer still to get an adjustable block? I’ve been doing this a long time and used a lot of products. You mention superlative arms? Funny cause that’s the same guy that left tons of us high and dry with shitty carbon locked Syrac blocks. Nope I won’t be giving him another dime of my money. That’s from first hand experience.

It’s as if you don’t understand the difference between a skeptic and ignorance. I am skeptical but you so far have only seemed ignorant. Am I wrong?

Please answer the following:

1. Your personal experience with OSS.

2. Anyone who has reviewed it and said wasn’t worth the trade offs or price of admission.

Thanks.

 

[LeadZeke]

As I suspected, you are hopping from topic to topic when proven wrong. Red herrings are a very poor and transparent fallacy. Each and every claim you've made has been shown to be wrong, and you've yet to deal with the core of the matter at all. Namely that as shown above, on an AR15 or AR10 with a Superlative Arms adjustable gas block a traditional can will be (assuming proper selection is done):

1.) Quieter at the muzzle.

2.) Quieter at the shooter's ear.

3.) Lighter (depending on can of course, but easy to do).

4.) Shorter (again depending on can but most will be).

5.) Less flashy.

6.) Won't require maintenance.

7.) Have access to more QD systems.

8.) Cheaper (depend on can).

In other words, there is no reason to get an OSS unless you cannot run an such a block (like on a shorter KAC for example). You can dance around this all you like, but the truth is obvious.

As for you latest round of fallacious bunk:

I did address those people using the cans, as I said they don't use adjustable gas blocks. So thanks for showing us you are in fact not reading.

I have used OSS cans new and prior gen, and I like them quite a bit in the right application. Which is to say anytime an adjustable gas block isn't an option, or the host isn't an AR15 or AR10 or bolt gun then it is pretty much as good as it gets for most end users. I'll probably be buying their Magnum can for a .300 Norma semi-auto. I also recommend them all the time to friends that get X95s as those are absolutely horrid with traditional cans, same with folks who are issues rifles with FSBs and cannot replace them.

So yet again we see that you are no skeptic, and that you are just here to spew marketing lines rather than engage in good faith. When you are capable of reading through a post completely, and watching a few minutes of youtube video give a shout.

Omg ???

Wait you’re going to get one???

A. You didn’t answer any of my questions. But accuse me of fallacies.

B. You’re still talking about adjustable gas blocks. Do you know the history of Superlative arms owner? You’ve referenced it twice. You’ve declined to answer most of my actual questions.

C. Your posts are the definition of a fallacy. Rather than addressing it you’re dancing around other subjects.

I suspect you’ll go on and on so I’ll let you have the last word. I’ll just leave this right here: AFTER ALL OF THAT, TURNS OUT YOU’VE ACTUALLY USED ONE AND INTEND TO BUY ANOTHER?

Too good man. Too good. ???

I’m out.

 

[LeadZeke]

Wow, I gave you another chance to simply read and instead you just continue on the same fallacious track. Sad. Should have stayed in school.

If you'd actually read the post, you'd know I answered all your questions.

Imagine nothing being a brainless fanboy and understanding that mission drives gear. Yes, I like OSS cans a lot and am very glad they exist. Doesn't make them a good idea on ARs when you can use an adjustable gas block (which is almost always). Just like I really like TT optics but I wouldn't put one of their 5-25x on my 10.5 and run around in buildings. Just like I wouldn't put a TBAC Ultra 9 on a Tavor. Not hard to understand and a very obvious conclusion based on the data if you A.) bothered to consult it and B.) weren't just a corporate cheerleader.

If you want to run an OSS on an AR or a bolt gun, it isn't like it is going to suck, it is just going to be significantly sub-optimal in comparison to the competition.

You couldn't define fallacies correctly if you tried, but thanks for playing.

 

[wyld3man]

I wouldn’t say the only reason to use an OSS can on an AR is if you don’t have an adjustable gas black, that’s just being short sighted. If you want to know my point of view on why I am mentioning that look at the first page of this thread and find one of my earlier posts.

 

[fortsbest]

I don't have one but plan on ordering one shortly. If it's any help, I recently attended a Nations Best sporting goods show and spoke to several gun and component reps. The one that struck the most impressive note was when I spoke to a Barrett rep. I was telling him I was looking at various suppressors and his comment to me was if it were for a bolt gun I should buy one of theirs. If it were for any type of gas gun, OSS hands down. They have fairly informative videos on youtube regarding various tests and sound information. Just thought I'd throw this in. Personally, I'm getting the HX-QD 7.62. Their wensite said it was designed with the U.S. Army CSASS requirements in mind, so there's that.

 

[richthe1]

I've actually been doing some serious thinking about getting one of the HX-QD Magnum TI ones so I can run it for everything from .338 on down.
(I just ordered a HX-QD 556)

Also thinking about either the HX-QD 762 TI as a second option if the first is not available.

Have you seen either of those in action on AI rifles & AR type platforms or just the HX-QD 762 ?

Thanks.

Did you end up doing this? I was considering running an HX-QD Magnum TI as my first can for a “do all” rifle can.
Thought it’d be nice for LMT rifles (both in 5.56 and 308) as they don’t really have a way to adjust for gas and can be “overgassed” and from what I’ve heard these low back pressure flow through cans from OSS seem to work well for that issue. I’d also be running it on bolt and want the capability of moving up to 338. Just not sure how this Magnum can would sound on AR15 and AR10 rifles.

Not sure if it would be better to (1) get this can for all - AR15, AR10, and Bolt, or (2) get the TBAC 338 For the Bolt + an OSS HX-QD 7.62 for the gas guns. Option 2 is quite a bit pricier.

 

[W54/XM-388]

The QD Magnum TI is the one I'm going with as soon as I can find one locally or from a local decent trustworthy dealer to buy (who actually cares to get back to me and not just blow folks off).

 

[Viper1973]

I have an OSS HX556 QD on my Tavor x95 and absolutely love it. On that particular gun it makes it ridiculously quiet. I had my doubts when purchasing but IWI insisted I’d be very happy. They didn’t lie.

I actually ended up buying more OSS cans due to the experience. OSS is legit and makes awesome stuff. You just have to know they don’t chase numbers they go for a complete signature reduction package like Surefire does... and they nail it.

Go option 2. Definitely nothing wrong wanting to save a few bux where you can, but you'll be happy with how stupid quiet that 338 TBAC is on your future larger caliber bolt guns. And it's just smart to have a 7.62 can to cover the Semi's. It really gets to be a PITA moving 1 single can around a multitude of hosts. They get hot, and it quickly starts to feel limiting. I guarantee you will end up with 2 cans or more at some point regardless. Save the agony of 2x the wait period. Pick a couple cans and purchase as close together as you can reasonably afford.

 

[Dlgies]

I find some of the comments here very entertaining. Seems people really like, or hate, OSS Suppressors. OSS makes very good suppressors but they are not for everyone. I’ve had the privilege of shooting several different suppressors in the military, law-enforcement and as a SWAT officer. We recently tested 3 suppressors to determine which one to purchase for our 34 SBR’s (10.5”).

OSS meters on par with most K cans. They are not as quiet as a full-sized baffle can. I recently compared the OSS 556K, YHM Turbo K, and a traditional full-size baffle can. The traditional can was a 7.3” long direct thread. I’m not listing the name because it is from a small company and it was not selected. I don’t want people to think that is because it is not a good suppressor. All 3 cans metered at 142db +/- 2 at the shooters ear. OSS and YHM metered at 145db +/- 1db at the muzzle. The baffle can metered 141 at the muzzle.

The difference in blowback was substantial on our 10.5” 5.56 rifles. The OSS can provided very little additional blowback and no perceivable rate of fire change on full-auto. The YHM Turbo K provided some additional blow back, though not bad. It noticeably increased the rate of fire on full auto. The traditional baffle can provide an extreme amount of blowback, making it difficult to fire multiple shots in a row. It’s significantly sped up at the rate of fire on full auto. It should be noted this gun was not tuned for a suppressor.

These results were not surprising and were on par with my previous experience with suppressors. Ultimately, we chose the OSS 556K for our short-barreled patrol rifles. No, it’s not the quietest, but it offers reasonable protection to the shooter and bystanders and is significantly better than going un-suppressed. It will allow officers to continue to communicate after firing their rifle (we tried several shots without hearing protection and had no ringing in the ears or issues). The lack of blowback, coupled with the fact that I don’t have to tune each rifle to the suppressor, made it a clear choice. It also allows the rifles to run cleaner and cooler (compared to other suppressors) which will aid in reliability and decrease the accelerated parts wear found with suppressors that increase the cyclic rate. The OSS QD mount is very simple, yet effective. We have had no issues with suppressors coming loose.

In my opinion, OSS is the best choice for semi automatic rifles, whether DI or piston. We have been very happy with our choice. Accuracy is unaffected (We run red dots with a Magnifier and are not getting exceptional accuracy to begin with. Average shooter is getting 2-3” at 100 yards). Return to zero/point of impact is very good after removing the suppressors and putting them back on.

On a side note, we selected the SilencerCo Omega for our sniper rifles. The OSS advantage is really lost on bolt guns.

 

[westsidecamper]

Just got mine and tried it out with 300 blk subs out of a 10" barrel. 220 grain berry's plated bullets over 9.9 grains of h4198. It was pretty quiet but I did use ear pro because I was at an open range. The action noise was definitely the loudest part. Zero increase in noticeable blowback while shooting nose to charging handle. I get gas to the face even with M193 unsuppressed, so this was a very pleasant experience. I did not scientifically test these but will eventually do a subjective test against a Dead Air Wolfman, which is supposed to be pretty good on 300 blk subs.

[Hyintensity]

I do. I have 2 and love both. 7.62 and 5.56 w/flash cap
I also have 10 other cans to compare to. (DA, Rugged, TBAC, Sig, Surefire, etc)

The OSS is a treat on all my semi autos.
There are pros and cons to all the cans out there. But the OSS pros FAR exceed the cons.

After 1.5yrs of owning a 7.62 Helix, I can say it lives on my semi autos and gets used far more than my other baffle cans. In reality, I have 10 other cans that sit unused because the OSS just stays on my most used seminauto.
While it is a little louder than other cans, this loudness is irrelevant due to the fact I wear ear pro anyway. And it is only a little louder. It still sounds like a suppressed rifle.

The gun runs very clean. The actions cycle very smooth. There is no tuning required past what the manufacturer did.

I simply can't say enough good about the OSS system

The new 556 can with flash hider is better than the older non flash hider version, but the old one isn't terrible.

If you want range time, high(er) round counts, clean, reliable guns, the OSS is excellent and I highly recommend it.

If you are in actual combat, the flash on the 7.62 not the 5.56 is a consideration.

I can say that all the heavily opinionated comments about the OSS are not based in experience, only what they have read on the internet.
I love mine. I bought a second because I liked the first so much. I will buy a 3rd too when OSS puts the flash cap on the 7.62 version.

All it takes is one day at the range behind a OSS suppressed AR with no gas in the face, no tuning the gas block, no over speeding bolts, no double feeds, clean weapons, no re-adjusting the gas block, no carbon lock, no loosening suppressors, no problems of any kind, and you quickly fall in love with the OSS system.

I highly recommend them

Looking at the latest OSS HX-QD 762 (maybe Titanium version). Not a whole lot of info I can find outside of the manufacturer.

Anyone here have hands on experience with one mounted to a precision rifle?

I highly recommend them

Hyintensity, not sure if I caught it but do you have 2 OSS cans? And 10 others to compare it to?

Anyone arguing sound suppression on a precision rifle board, when we are talking about shooting full power loads is wasting everyone's time. It's a Fool's Errand ...

Nobody "hears" them the same way, it's almost always tone-related more so than an actual difference that will resonate beyond the shooter. It's the line of guys standing 10ft behind the shooter weighing in on which one "sounds" better ... silly I say. If one can is measuring 140db and the other is measuring 146db big fucking deal, both still require ear pro if you are shooting more than 2 rounds, so it's a wash. If you said, Can A, B, C, were 133db and Can OSS was 149 dB you might have a debatable point, but these are usually pretty darn close to each other. Single-digit variations are nothing.

The OSS cans are pretty awesome and tend to be one of my go-to cans lately ... why, accuracy, they don't ruin my accuracy. Plus I like the reverse threads.

Pew Science has reviewed the OSS. Its claim to fame is metering close to a lot of similarly sized cans while imposing very little backpressure, which only matters on semi-auto. But there are much quieter cans.

OSS HX-QD 762 .308 Suppressor Test — PEW Science

OSS HX-QD 762 Silencer Test with back pressure data. Real sound signature data with the Suppression Rating from PEW Science. Hearing Safe determinations for your use case. How does it do as a 308 rifle suppressor? Can it suppress 7.62 NATO? Is it the best 308 hunting suppressor? How is the back

pewscience.com

The goal of Pew Science sound standard is to be a total sound dosimeter for your ear - think xray dosimeter. Raw decibels can be found in the reviews, but raw decibels don't tell the tale, exactly what you're saying with regard to tone. A single peak decibel impulse is an indicator, but not the whole story of what it's doing to your ears.

Pew has seen a lot of support in part because no one from industry has actually challenged the results. SilencerShop sponsors Jay's podcast and he's worked with a lot of industry. He's also talked about potential factors in silencer accuracy on his podcast, e.g. things like symmetric baffles (OSS, TBAC, Q are a few of those).

The current top of that sound testing is the CGS Hyperion, also symmetric, Sig 25° taper 5/8x24 direct thread, so hand tight with no backing off and perfect concentricity. 15.1oz. Quieter than an Ultra 9. 3D printed DMLS Titanium, coaxial chambers that separate and remix gasses.. more going on than a typical stack of baffles. Hyperion is also the highest backpressure can - not a concern on a bolt gun, but backpressure is how most every can other than the OSS attenuates sound, by trapping gas.

The OSS bleeds energy from the gasses by running them through a long roughened path, rather than by compressing them into the baffles. Maybe that helps contribute to accuracy, or maybe not. The OSS is amazing in that it is still as effective as similarly sized, older can designs - quieter than a Silencerco Harvester 300, i.e. legit quiet. CGS/TBAC still much quieter. It would be really interesting to see meaningful accuracy testing done to cans the way Pew is doing sound testing for them.

I have a oss hx 762 ti can in jail...During the wait I second guessed myself and started looking for traditional cans but kept coming back to oss...day 226 and counting

 

[Hyintensity]

Hyintensity, not sure if I caught it but do you have 2 OSS cans? And 10 others to compare it to?

Sorry for the confusion.
I have the Helix 7.62 Ti and 5.56ti. I also have an assortment of other cans like Sandmans, Nomads (reg and long), Wolfman (used in "rifle mode"), TBACs, and a few others. I think "10 others" includes some other 22 and 9mm cans.

I got sick of reading all the nonsense posts (and other internet experts) who have no 1st hand experience so I spent the last few years getting 1st hand experience.
Like the guy posting the video of Mrgunsngear video showing great performance and Mrgunsngear saying the OSS was excellent on an AR10. And saying OSS sucks just because it's a little louder.

The way I determine which products I like is by how much I notice them while using them. If there are no hassles and the performance is great, then the product sticks around. If I have lots of issues, I move on.

I put the OSS on my AR over a year ago and haven't switched it out. I have added OSS mounts to 3 additional gas guns.
Heck, I just got a new Nomad Ti a month ago and don't have any plans on installing it on any gas guns I have.
At this point, the only future cans I will switch the OSS out for is updated OSS cans.

My baffle cans now sit waiting for neat bolt gun setups like an Elf Owl and specialized gas guns or dedicated hunting setups.

 

[Lowlight]

Nerds argue about sound because they can't focus on the other parts of the equation, mainly the shooting parts.

To them, all the cans work the same, they only discuss sound suppression because it would ruin a bunch of manufacturers when people saw just how bad they made their rifle shoot. Not all cans are created equal and that includes how they handle performance in terms of shooting. The mounting, the repeatability, the changes in terms of accuracy should be key, the recoil pulse and its effect on accuracy and recoil management from the shooter's perspective. All that has a bearing.

Sound is only one part of the equation and not the most important part.

 

[heavy65]

No one's arguing about sound anymore, at least from cans for which Pew Science reviews exist. If a can doesn't reduce sound, there's no point in running one, even if attenuating sound is only part of the equation - the first, fundamental part. But once you know how quiet it actually is, the argument over that is moot. Those reviews allow people to focus on the important parts like you're saying, except for the first time starting from a set of realistic expectations about relative can performance, also like you're saying.

Jay's demystified sound the way Litz demystified G7. Nerds like those settle debates, it's left to others to perpetuate or disregard them. Somewhere out there is another nerd who might similarly quantify precision potential in a can, standing on the shoulders of their work. Jay's offered to work with anyone willing to put in the rigor to do that. The Omega backpressure metric and how that informs flash signature is a likely direction for future testing. If you know how the gas is flowing, you may be able to correlate that with flash output. You're already measuring how much and how fast stuff is jetting from the muzzle. It may not be the greatest leap from there to understanding how that same flow of stuff from the muzzle is affecting recoil.

[Ape_Factory]

I've had my 762Ti for a few weeks now and I have zero complaints. Noise behind the gun, when actually shooting it, is quite different from viewing as a spectator. I use it on three AR gas guns, a .308, 300 Blk and a 5.56. and watching others shooting, it's much quieter standing to the side than shooting IMO, mostly because you're hearing the gun cycling up close and personal. But everything about the can is fantastic. And the fact the gun will function with no changes to the gas system is just a bonus. Just makes every trip to the range more enjoyable with no increase in gas to the face and the overall lower DB's. I know the guys in the booth next to me appreciate the can as opposed to the muzzle brake on the .308. And it's stupid quiet with the 300 blackout and subs. Laugh out loud quiet.

After my last visit to the range, it does not affect accuracy at all although there is a POI shift on/off. I had a 1-4X LVPO on the 300 Blk with what was essentially a 223/5.56 reticle so the drops didn't work for the 300 blackout rounds, subs or otherwise. Shooting at 100 yards, and given the width of the reticle lines, I was pretty much guessing where the subs were hitting on the target and drop point on the reticle. Was shooting out of the box S&B 220gr subs and shot an 8 or 10 string group as quick as I could get away with at the range. When I retrieved the target I was surprised that I'd basically just put that many off the shelf low cost rounds (relative!) into a 1 MOA group. They were all right on top of one and other. 10.5" barrel with the OSS suppressor. Happy camper.

I have had the same experience with my 2 OSS cans.

It's funny seeing all the internet hate when I have had a hassle free and very pleasant experience with all expectations living up to the features that originally attracted me to the OSS.

It makes all my gas/piston guns a treat to shoot.

Speaking of piston guns, I'm very, very interested in running an OSS on x39/x54R AKs. The only reason I don't have an OSS in NFA jail yet is because I'm waiting for Pew Science to test the Magnum (longer) version of the Helix QD-Ti. One of the most interesting things in Jay's testing has been to see how the different can designs scale their performance with added length. I would expect OSS performance to scale quite well with extra inches, given how it ultimately relies on the length of the gas path rather than managing the gas pressure curve via restrictive baffles. On say a 23" Vepr 7.62x54R with a KNS piston, I have irrationally high hopes.. but if it turns out that the Magnum doesn't add much to 308-class performance in testing, then I'll stick with the regular length, lighter Helix that will be handier on AKs.

The CGS Helios QD Ti will be the next can I buy no matter what (Q3 release). A shorter Hyperion with 1.375x24 mounting. Micron level concentricity by virtue of its DMLS 3D printed design - no lining up even an EDM cut. Will require host tuning, but delivers typical 8.5" can performance in a 6.5" package, in a design more durable than typical Ti cans. A CGS Helios QD Ti with an Area 419 adapter is going to be the overall "general purpose" setup to beat IMO - provided that host tuning is on the table, or the host is not backpressure sensitive. Otherwise the OSS will likely remain the one to beat.

One of the features of the Helios is that you can add a "vented" endcap, which vents its outer coaxial chamber to atmosphere. This gets it to OSS levels of very low backpressure, but in that "vented" mode, the OSS performs far, far quieter than the Helios. This just goes to show how effective the OSS approach really is, given that the [edit:]Helios with a "solid" endcap handily outperforms everything in its size class.

 

[TheOfficeT-Rex]

My OSS 762 is in jail, but I'm also hoping to run it on an AK platform. It will replace a SRVV jet brake, if Silencershop ever ships my backordered LHm14 brake... Wonder if it would have just been faster to order from OSS website direct.

 

[PBWalsh]

Hopefully mine will come this year. Stamp cash got cashed in April(ish).

 

[heavy65]

Silly, but I can't help but appreciate how the OSS muzzle brake isn't too far off in appearance from say the PSL's. You could cancel your backorder and order from one of these in-stock places:

The only Helios QD vented front caps that've been tested are the full vent front cap and the solid front cap on a 308 bolt gun. Two entirely different ends of the spectrum. There are other front caps with various different features and vent quantity and sizing and adjustability which allow the end user to tune the Helios/Hyperion series across the entire spectrum of sound, flash, and gas reduction. They'll eventually be made available in the future.

I'm assuming that not only will they be available, but that they'll also be tested by Pew Science. Really looking forward to see how CGS intermediate endcaps perform, but I'm planning around solid endcap either way.

I ran it a bit on an NPAP using a 5/8-24 adapter from KN Precision and was really pleased with it.

My piston guns are PWS variants (556, 300blk, x39) so they all suppress very well because they are designed to do so.
With the OSS, I don't need to run them in their suppressed settings. I run them in their open/normal settings.

My personal experience with the 762 Ti and 220 grain 300 blackout subs (tried more than one bullet and powder combo) was not great. Not bad but not as good as a full length Wolfman. I tried it on a 16 inch Ruger American, a 16 inch Savage Axis, and a 10" SBR AR.

 

[Ape_Factory]

My 300 blackout is a 10.5" barrel with a LW BCG and a SA gas block. I am currently using Berry's 220gr with CFE BLK for plinking and still testing Hornady 190gr. Sub-X with the same powder, trying to find that magic load. Tula primers. I honestly can't tell any difference between various subsonic factory loads from a noise standpoint but I do wear ear protection and am hard of hearing according to the wife. S&B's have been stupid accurate at 100 yards but really sound no different than Hornady Sub-X. I measure all the factory ammo and the last box of Hornady Sub-X was not consistent from a dimensional standpoint at all. I haven't gone into bleed mode on the SA gas block but I may try that as well to see what sort of difference it makes.

 

[ksp 498]

Thought I’d chime in with my results. Rifle is a Gap 10 G2 16.5 inch barrel with Seekins select adjustable gas block. Prior to OSS 763 Ti I was using a Ultra 5 on it. After about 20 rounds with the Ultra 5 inside of the rifle was pretty dry and had a lot of carbon in the receiver. Also rounds in the magazine had carbon on them. With the OSS 762 Ti, the receiver is a lot cleaner, magazine is cleaner, and you do notice less blowback. After 50 plus rounds the bolt is still wet with lube. With the Ultra 50 it would be dry. As far as accuracy goes it’s the same as the Ultra 5. The brake has been staying clean, and the van is easy to removed once shooting is complete. Suppressor is taken off when stored and first round to 50th is the same when mounting the suppressor. There is a zero shift when unsuppressed, but I always run the suppressor so it’s not a big deal. As far as do I like it yes. Better then the Ultra 5 on the same rifle..yes. Is it louder? I can’t tell, but for a working can I don’t care lol. At the range I’m using ear pro anyways and for that couple of shots I may need to take without ear pro I can’t tell a difference, it’s not blowing my ears out like a brake or unsurpassed rifle. Overall I like it. Also have a OSS 556K on a 10.3 416 and it too runs better then the previous AAC suppressors. Overall my experience with the suppressors have been positive.

 

[Triprack]

Looking at the latest OSS HX-QD 762 (maybe Titanium version). Not a whole lot of info I can find outside of the manufacturer.

Anyone here have hands on experience with one mounted to a precision rifle?

For HK MR762, the OSS is the only can which will work properly and consistently. Non-flow-thru cans speed up the BCG way too fast and nothing good happens then. Tested in-house.
